Since my HP-35S used to devour batteries I've set it on diet on my shelf where it's collecting dust now.

Anyway, I didn't use the EQN feature before. And I'm sure there are people here who (did) use their HP-42S SOLVER more than I do. I'm just wondering what's the added value of EQN to the HP-42S solving paradigm (if any).
